摘要 目的 :建立和鉴定一种新型腹主动脉瘤动物模型 ,为腹主动脉瘤的进一步研究提供基础。方法 :选取豚鼠肾下腹主动脉组织 1cm ,正位替换SD大鼠同长度腹主动脉 ;SD大鼠腹主动脉原位离断后吻合分别作为对照。分别于术后 4周动态观测和比较移植腹主动脉直径、腔面积等形态学变化 ;计算机图像技术半定量分析弹力纤维、胶原纤维及平滑肌变化。结果 :存活受体中 88%移植腹部主动脉血流通畅 ,无移植物或吻合口狭窄 ,无腔内血栓形成。 4周内 ,异种移植组腹主动脉直径随时间延长逐渐扩张 ,与对照组有显著差异 ;腹主动脉扩张率与弹力蛋白、中膜平滑肌变化呈现显著负相关。结论 :免疫炎症损伤介导的豚鼠 -SD大鼠异种移植腹主动脉瘤是一稳定可靠的动物模型。
